Background

The external auditory canal is an S-shaped bent curve from an external auditory portal to a tympanic membrane, is 2.5-3.5 cm long, and is from the outer side to the inner side, the external auditory canal tends to move forwards and upwards firstly, then turns to the rear side and finally moves forwards and downwards, the outer side 1/3 of the external auditory canal is a cartilage part which is continued with a soft tube of an auricle; medial side 2/3 is a bony part and is an elliptical short tube surrounded by temporal scales and a drum. Since the cartilaginous part is moved by pulling the auricle, the auricle is pulled backward and upward to straighten the external auditory canal when the external auditory canal and the tympanic membrane are examined. The external auditory canal of the infant is almost supported by cartilage, is short and straight, the tympanic membrane is nearly horizontal, and the auricle needs to be pulled backwards and downwards during examination.

The external auditory canal surface is covered with a thin layer of skin, the cartilage skin contains abundant sensory nerve endings, hair follicles, sebaceous glands and cerumen glands, the yellow brown sticky substance secreted by the cerumen glands is called cerumen, and the cerumen formed after drying can block the external auditory canal and influence the hearing. The subcutaneous tissue of the external auditory canal is few, the skin is tightly connected with the hose membrane and the periosteum and is not easy to move, so when the external auditory canal generates furuncle and swelling, the external auditory canal has severe pain due to large tension.

Current duct cleaning device mainly is washing clearance and negative pressure clearance, and the washing clearance is better to less, the lower secretion effect of viscosity, and to great or oily secretion, the effect is not obvious very much, and the negative pressure clearance is poor because of the visual effect of duct, and the operation is got up and is wasted time and energy.
